Thanks, another question...how do I open the ooma setup page (http://setup.ooma.com) when the Hub is behind the Router? when I check the Router's IP Table, it shows the IP for the Hub (the last digit of the MAC is different though) and I can't still open the setup page.

Temporarily connect your computer to the hub's home port and go to setup, and then to Advanced Settings. Copy the home port IP address (probably 172.27.35.1) to the hub's DMZ and save. Reconnect your computer as you normally would to your router. You can now access setup by entering the IP your router assigns to it in your browser, probably something like 192.168.xxx.xxx. So that you can always use the same IP to access setup, have your router assign a static IP to the hub.
